. lTo allwhomit may concern:

Beit known that I, SUZIUYL \VoLFsoN, re-

'f-siding at Zaschnick, Empire of Russia, have invented certain new and useful Improvements in Means for Utilizing Exhaust, of which the followingis a specification, refer "ence being bad therein to the accompanying.

' drawing, which shows the construction in vertical section.

As the steam coming from the steam-boiler contains a great part of water which is conducted to the steam-engine, a great quantity of warmth will be consumed by heating this water to the temperature of the steam. To remedy this inconvenience I have made an arrangement .by which the feeding-water gained the condensation (which contains, consequently, the above-mentioned water) is recon-- ducted, under a temperature as high as possible, to the generator. For that purpose, the steam coming from the engine leaves the cyli nder not with the pressure of the atmosphere, but with half the pressure of the fresh steam. This steam will'pass through a' series of tubes placed in a closed vessel filled with water.

The water then willcondense the steam passing through the tubes, and a continually-acting feeding-pump in communication with-the tubes presses the steam-water again into the certain tensiona little boiler or generator. The cold water in the vessel or low-pressure boiler will by-andby be heated over the boiling-point and produce a under the pressure in the tubes. As soon as the tension has reached a certain degree, a second cylinder may be driven by the steam'thns Formed, and so 101)- tain a kind of compound engine. The stroke intervals of both cylinders are quite independent of each other, and therefore one can construct in this manner asystem of engines workingwith two cranks mounted under a right angle against each other. Thus I obtain'a perfect'ntilization of the heat. The temperature of the fresh steam does not much difi'er from that of the steam coming from the first cylinder, and the water is pressed by the feeding pump into the generator with a temperature corresponding to the tension of the steam only 7 heated directly by the fire, is continually fed the steam coming with water prothisvessel. However, the sediment will be.

deposited on the outside of the tubes, and can be easily taken away. In .the low-pressure boiler the steam is formed by the heat of the steam passing through the tubes. The difference between the tension inthe low-pressure boiler and the tension 5f the steam passing through the tubes isdependent on the heating-surface represented by the tubes portion to the quantity of the condensed steam. The full heat of the steam coming from the first cylinder being employed in the formation of steam in the low-pressure boiler, while in prothe tension in this boiler is a little lower, the

quantity of this steam is therefore larger.

The low-pressure boiler is acting here in the place of a receiver of a the advantage that it furnishes besides afeed-- ing-water of high temperaturefor the generator.

On the accompanying drawing, A isa winding-tube generator heated by fire. The steam is conducted by the tube b, to' the cylinder 0. The steam coming from this cylinder passes through the tube binto the chamber K, and

thence into the tubes I), placed in the. condenser or lowpressure boiler B, heating the water in it. .The condensed-steam water is collected in' the "essel W, where it is taken compound engine, with i through the tube 0 by the feeding-pump E and reconducted to the generator A through the tube a. The steam formed in the low-pressure boiler B is conducted by the tube b into the second cylinder, D, where it is acting like directly from the first cylinder. l

w and w are water-glasses, to indicate the height of the water in the vessels W and B.

s is a feedingtube for the 'lowpressure boiler, and s is a reserve feeding-tube for the vessel W. A

I'claim-- '1. The combination of the generator A, the

tube a, the cylinder 0, connecting therewith, l ator A, the lew-prcssure boiler B, having a. 10 the tube 11, the low'pressure boiler B, connect water vessel or chamber, as described, and the ing therewith, the water-vessel \V at the lower tubes and pump to return the condensed water end of .the boiler, the tubes 6 and a, and the to the generator, and the generator, substanpnmp E, connected therewith to return the tially as described. condensed water to the generator, all substantiall'y as described.

2. lhe combination of the cylinders O and B. ROI, D and their connecting-tubes with the gener- TH. LORENZ.
